![]() Its development is totally “open source” and is proposed as a kit made up of electronic components, based on Arduino and easy to access mechanical components in the market. This work detailed the design and validation of a DLP (Digital Light Processing) 3D printer, using backlit LCD (Liquid Crystal Display) screens with ultraviolet light. However, due to its high cost, it is a technology that is difficult to introduce in small artistic foundries. An alternative to solve this limitation, is to use a DMLS (Direct Metal Laser Sintering) 3D printer. These sizes and resolutions are not suitable for creating microsculptures used, in many cases, in jewelry. However, models printed by PLA are limited to approximate minimum sizes of 3 cm, and the optimal layer height resolution is 0.1 mm. Pieces modeled by computer and made with FDM (Fused Deposition Modeling) 3D printers that use PLA (polylactic acid) can be implemented in the procedures of artistic casting. The adoption of open-source digital manufacturing technologies in small art workshops may improve their competitiveness. ![]()
